Ionic current noise in quartz-substrate-based nanopore.

(a), RMS ionic current noise through 20-nm-thick SiNx membrane on various substrates. (b), Power spectrum of SiNx 20 nm on Si and a-Si 200 nm/quartz 200 μm measured in 1 M KCl while maintaining a pore current of 0 and 4.5 nA, respectively. (c), Baseline ionic current noise traces corresponding to the PSD curved structures described in (b).
